Ive invested in D lock and a hardened chain... If a thief really wants your bike, the thief is going to get it. The question is how fast can they get it, that's what determines if they go for your expensive bike, or the poor buggers next to yours. They're not going to hang around long. Having different locks requires different tools so even the most experience hard attacker or lock picker will likely walk on by if he sees he needs 2 different methods of getting access to your bike. The downside of course is the inconvenience and weight of such items. Only you can decide what matters most...
